New Classification of Focal Cortical Dysplasia: Application to Practical Diagnosis Yoon-Sung Bae, MD1, Hoon-Chul Kang, MD, PhD2, Heung Dong Kim, MD, PhD 2, Se Hoon Kim, MD, PhD 1 1Department of Pathology, Yonsei University College of Medicine, 2Division of Pediatric Neurology, Department of It is of great significance to correct diagnosis for FCDⅡ. Malformation of cortical development (MCD) accounts for the majority of drug⁃resistant epilepsy, focal cortica ldysplasia type Ⅱ (FCDⅡ) is the most common and most characteristic. Epub 2005 Sep 19. From a group of patients with intractable frontal lobe epilepsy, we selected patients with neuroimaging diagnosis of FCD. In this paper, a computer aided diagnosis (CAD) system for automatic detection of focal cortical dysplasia (FCD) on T1-weighted MRI is proposed. But, the diagnosis was confirmed to be Taylor type IIb. BACKGROUND AND PURPOSE: Focal cortical dysplasia (FCD) covers a spectrum of con-ditions in which the neuropathologic and electroclinic presentations and the surgical outcomes vary. However, there are so many diseases which are similar with FCD Ⅱ in morphology and immune phenotype, such as tuberous sclerosis complex (TSC), hemimegalencephaly (HME), etc. Neuroimaging of focal cortical dysplasia.

Focal cortical dysplasia is marked by cortical architectural abnormalities secondary to disruptions of cortical development. Enhanced visualization of blurred gray-white matter junctions in focal cortical dysplasia by voxel-based 3D MRI analysis. Background. Knowledge of focal cortical dysplasia magnetic resonance imaging (MRI) characteristics is of utmost importance for diagnosis. Categorization of lesions of the tibia into those that cause cortical destruction and those that cause cortical proliferation can help narrow the broad differential diagnosis. Colombo N, Tassi L, Galli C, Citterio A, Lo Russo G, Scialfa G, Spreafico R. AJNR Am J Neuroradiol. Malformation of cortical development is a broad term for a variety of developmental cortical anomalies frequently associated with epilepsy (1). The aim of this study was to identify the MR features of histologic subtypes of … Differential diagnosis. epileptic seizures. NLM Neuroradiologic findings in focal cortical dysplasia: histologic correlation with surgically resected specimens. Focal cortical dysplasia (FCD) is a malformation of cortical development (MCD) and is also one of the most common causes of intractable epilepsy that was defined by Taylor et al. Typical vascular proliferation may be detectable with MRI and suggests the diagnosis of FCD with glial proliferation. To establish the contribution of multiplanar reconstruction (MPR) and curvilinear reformatting (CR) to the MRI investigation of focal cortical dysplasia (FCD). Providing automated procedures to detect FCD lesions is greatly desirable because visual diagnosis is often challenging, time consuming, and relies highly on the individual's expertise. This is a case of Atypical Taylor type IIb Focal cortical dysplasia. Focal cortical dysplasia (FCD), a malformation of cortical development, is regarded as a major cause of pharmacoresistant epilepsy with high seizure frequency. The most common findings are cortical or subcortical hyperintensities especially seen on FLAIR-images. Epilepsy Behav. Blurring of the corticomedullary junction was present in 5 patients. Age of presentation, usually with epilepsy depends on, to a degree on the type of cortical dysplasia, with type I (see below) more frequently presenting in adulthood 4. Finding on brain MRI mimicking focal cortical dysplasia in early Rasmussen's encephalitis: a case report and review. To describe MRI findings of four types of focal cortical dysplasia (FCD) and compare them with diagnostic criteria reported in the literature. Imaging characteristics of FCD type I: Atrophy - lobar or sub-lobar, with regional loss of subcortical white matter examined the brain bank and found that focal cortical dysplasia was the most common diagnosis among children (39.3%) and hippocampal sclerosis was the most common histopathological diagnosis among adults (44.5%) (Blümcke et al., 2017). In one patient, MRI demonstrated vascular proliferation within the FCD. Focal means that it is limited to a focal zone in any lobe. Focal cortical dysplasia is a common cause of intractable epilepsy in children and is a frequent cause of epilepsy in adults. We introduce a new set of differential cluster-wise features comparing local differences of the candidate lesional area with its surroundings and other GM/WM boundaries. Three major stages generally are recognized: (i) proliferation of undifferentiated cells in the neuroepithelium; (ii) migration of neuroblasts; and (iii) cell differentiation. Such malformations are ass… Focal cortical dysplasias: MR imaging, histopathologic, and clinical correlations in surgically treated patients with epilepsy. 2006 Jul;16(3):185-96. doi: 10.1111/j.1552-6569.2006.00025.x. Discussion: Matsuda K, Mihara T, Tottori T, Otubo T, Usui N, Baba K, Matsuyama N, Yagi K. Huppertz HJ, Grimm C, Fauser S, Kassubek J, Mader I, Hochmuth A, Spreer J, Schulze-Bonhage A. Ingmar et al. Hippocampal and parahippocampal regions were normal. It is variably associated with other features of focal cortical dysplasia, such as cortical thickening, blurred grey/white junction and decreased T1 signal (see focal cortical dysplasia article). 1, 2 FCD is assumed to result from disturbances during prenatal and perinatal cortical development resulting in cortical dyslamination and the occurrence of dysmorphic neurons and/or balloon cells (BCs). The final organization of the cortical mantle is the result a series of partially overlapping prenatal developmental processes. Patients were selected on the basis of a proven histopathological diagnosis of type I focal cortical dysplasia (FCD I), alone or associated with other lesions.  |  This study aimed to determine the diagnostic contribution of cranial MRI and the apparent diffusion coefficient (ADC) in FCD. Its signal was hyperintense on T 2 -weighted and FLAIR images, but variable on T 1 -weighted images. Focal cortical dysplasia (FCD) is a condition that often interferes with the cranial mass. BACKGROUND Focal cortical dysplasia (FCD) was first described in human beings in 1971 (Taylor and others 1971) when microscopic abnormalities, including large bizarre neurons and cortical disorganisation, were Typical vascular proliferation may be detectable with MRI and suggests the diagnosis of FCD … Thickening and hyperintensity of the cortex on T 2 -weighted and FLAIR images are more reliable signs of FCD than blurring of the gray matter-white matter junction and signal changes on T 1 -weighted images. There were no other abnormalities in the brain. Differential Expression Hallmarks of Interneurons in Different Types of Focal Cortical Dysplasia Chao Liang1 & Chun-Qing Zhang1 & Xin Chen2 & Lu-Kang Wang1 & Jiong Yue1 & Ning An1 & Lei Zhang3 & Shi-Yong Liu1 & Hui Yang1,4 Received: 7 August 2018/Accepted: 30 January 2020 2005 Oct-Nov;67(1-2):35-50. doi: 10.1016/j.eplepsyres.2005.07.009. 2003 Apr;24(4):724-33. Results: Author information: (1)Department of Pediatrics, Taipei Veterans General Hospital, Taipei 112, Taiwan. Focal cortical dysplasia (FCD) and mixed neuronal and glial tu- mors share many clinical characteristics; therefore, the presurgi- cal differential diagnosis of these diseases using MRI is difficult in some cases. Therefore, in addition to the ADC values and electroencephalography Thickening and hyperintensity of the cortex on T 2 -weighted and FLAIR images are more reliable signs of FCD than blurring of the gray matter-white matter junction and signal changes on T 1 -weighted images. Focal cortical dysplasia (FCD) is a neuronal migration disorder and is a major cause of drug-resistant epilepsy.
